Looks good to me
Amazin smoker is not perfect. I have the big tube and have had it go out twice.
the design here is much more sophisticated. Cold smoke salmon simply has not tuned out for me with anazin smoker.
By the addition of the ice pack option, mounting outside the box and using all red alder one should be able to make nova lox as good as any commercial outfit.
I would noy bad mouth this unit until there is some evidence other than a swag.
(Scientific wild ass guess)
